SPRING-GUIDE.

Specification of Application filed April 23,

Lett P t n Patented Mar. '7, 1911.

1910. Serial No. 557,162.

To all whom it may concern:

lie it known that 'L Ja nss C. Learns, a citizen of the United States, residing at Philadelphia, in the countyof Philadelphia and State of Pennsylvania, have invented a certain new and useful Spring-G uide, of which the following is a specification.

This invention relates, broadly considered,- to springs such as are used in the construction of beds, couches, furniture, car-seats and the like, which are guarded or retained displacement.

The principal object of the present inventionmay be said to be the providing of a spring guide of neat, simple, durable, efficient and comparativelyinexpensive construction, which while being free to contract and expandqis held and guarded against lateral movement.

A' further objectof the present invention is to provide a spring guide in which the plunger thereof, while free to move up and down is retained against rotary movement.

A still further object of the present invention is to provide spring guide, which when to a bed, -c0uch,- furniture, car-seat, and the like, will in use enhance the comdue to the fact that the weight of the occupant upon-the spring will be evenly distributed in one direction only, that is downwardly and in contradistinction from downwardly and laterally.

Other objects of the invention relate to the providing of general details of construction and arrangement of-parts as will hereinafter more fully appear.

The invention consists of the improvements hereinafter described and finally claimed.

The nature, characteristic features, and

scopeof the invention will be more fully'un-.'

the following description derstood from taken in connectionwith the accompanying guide embodying the invention,

d-rawingsforming-part hereof and in which: Figure 1, is a view in elevation of a spring Fig. 2, is a view in central section of the same, Fig. 3, is a. top .or planviewofieFig. 1, Fig. 4, is a. View. in cross-section taken upon the line 4-4. of'lfiig. 2, and Fig, 5, is a view in central'section drawn to an enlarged scale, and illustrating the spring guide in contrac'ted position. i

Referring to the drawings, the spring guide ofthe invention is shown as comprising generally speaking a base, a plunger working therethrough and a cushion between the base and plunger. As shown the base comprises a circular plate 1, provided with apertures 2, for the reception of screws or place, a central aperture 3, being present, for a purpose to be presently described. Shown as formed integral with and surmounting the plate 1, isa portion 4, concentric with the plate 1, and forming a shoulder 5. The concentric port-loud, terminates in the upwardly extending standards (3, spaced as shown in Fig. 2, 'as of a width equal to the width of the opening 3, in the plate 1. The standards 6, are bridged as at 7, to parts of the spring guide- Tl centrally I therethrough in its upward and downward movement of the circular stem 9, wliich' is carried by the supporting disk 10, of the plunger parts. This stem 9, may be either formed integral or have other connection with the said supporting disk 10. a, is provided with a key way- 11, and the bridge part 7, is provided with a set screw 12, which normally engages said key Way whereby the plunger parts may move vertically with respect thereto. The lower portion of the stem 9, is provided with a laterally upward movement of the plunger parts.

Fitted between the baseand supporting plate of the spring guide is a coiled spring 14, the shoulder 5, of the base and the sho'ul der 15, of the supporting plate-serving to provide convenient means for retaining the spring in proper position. As clearly 1llus-. 'trated in the drawings,

which and the plate 17, which is arranged -1I1 a plane below that of said ring, smaller diameter, are inclined arms 18, openings 19, being present between the said base that is vertically and in contradistinotion from laterally. In

to permit of the stem 9, passing downthrough thebase parts. Thus the spring 14, always retains its shape and cannot caused'to a:'-' .e or respond to lateral movement. Clearly when the sprin the class above described are use in connec- The stem and of,

this connection, 'it' may be remarked, that the opening 3, servesthe like whereby the base may be secured to form a guide for the plunger 1e part 7,'i s.. apert-uredas at 8, for the passage extending pin 13, in order to limit the the supportingplate 10,compr1ses an annular ring 16, connecting arms. In operation the plunger parts move upward and downwardly with respect to the guides of occupant b i such sprin tion with beds, couches, furniture, car-seats and the like-they add to thecomfort ofthe reason of the fact that they provlde cus ion like devices that readily respond to the weight of the occupant in up and down direction only.- Obviously this-is importantbecause an article equipped with guides will not sag due to spring disp acemeiit, but will always maintain a uniform surface.

What I claim is:

1. An article of the class recited comprising a centrally apertured base, a'supporting element consisting of an annular ring having a plate arranged in a lower plane, said ring and plate being connected by arms, a stem depending'from said plate and working through said apertured base, said stem being afi'orded' vertical movement with respect to the base, but locked against lateral and rotary movement and a coiled spring between said base and supporting element.

2. An article of the class recited comprising' a centrally apertured base, a pair of standards rising from said base, a, centrally apertured bridge piece formed integral with said standards and spanning the base aperture, a supporting element consistin of an annular ring having a plate arrange in a lower plane, said ring and plate being con plane, said ring and plate plate and working vertically .t rough the bridge piece but locked against lateral and rotary movement and a coiled spring arranged between said base and supporting element.

3. An article of the class described comprising a centrally apertured base, a pair of standards rising therefrom, acentrally apertured bridge'piece, formed integral with said standards andspanning thebase aperture, said bridge piece having a key, a sup porting element consisting of an annular ring having a plate arran ed in a lower being connected by arms, openings being present between said arms, a depending stem carried by said plate having a key-way for cooperating with the key of the 'bridge piece working vertically through the bridge piece, a stop carried by said stem for limiting the up-.

ward movement of the supporting element and a coiled spring arranged between said' base and supporting element. In testimony. whereof I. have hereunto signed my name.
